pim-23a

PACKAGE RADIATION MONITORING SYSTEM

Model # PIM-23A

FEATURES:

AUTOMATIC CONVEYOR FOR PACKAGES

AUTOMATICALLY SEPARATES ITEMS ONTO ``CLEAN'' AND ``RADIOACTIVE/CONTAMINATED'' BELTS OR CHUTES

RADIATION TRIGGER POINT IS CONTINUOUSLY ADJUSTABLE

MANUAL OVERRIDE

FIVE ENERGY (REGIONS OF INTEREST) WINDOWS

SYSTEM DESCRIPTION: Model PIM-23A Package Radiation Monitor is a sturdy, dependable, long life mechanical system with advanced electronics.
Model PIM-23A is suitable for use in all package handling situations.
The detector is a 3'' x 3'' NaI Scintillator (Optional 5'' or 7'' diameter) and with its own electronics it gives great sensitivity.
Packages are physically sorted by the second conveyor onto ``CLEAN'' or ``RADIOACTIVE/CONTAMINATED'' belts or chutes. Image PIM-23A

PIM-23A

Numerical measurement results are saved to the 60 Gig hard drive and are easily accessible for all packages: clean and radioactive.

Color LCD computer monitor shows measurement values from all 5 Energy Isotopes. Indicating lights show status or step of operation and background. Ready to Count, New Package Moving into Position, Count in Progress, Count OK-CLEAN, or Count ALARM-RADIOACTIVE, ETC. The date, time and results of each package measured in that batch, that day, that week and that year are available for display, print-out and safe storage. Statistical reports are also created.

Automatic Mode is very similar to batch mode, but in Automatic Mode the packages are checked automatically, all day, or until there are no more packages to check. The test parameters can be changed in automatic mode, at the beginning of the day, or by activating the manual override.

Accessories: One set of calibration sources is supplied with PIM-23A Package Monitor. This consists of one each Ba-133, Cs-137, Co-60 calibration source standards. Each Source comes with NIST Traceable calibration certificate, test data, and Calibration Factors.

PACKAGE RADIATION MONITORING SYSTEM

Model # PIM-23A

SPECIFICATIONS:

Conveyors: Packages pass beside the detector, then packages are physically sorted onto "RADIOACTIVE/CONTAMINATED" Belt and "CLEAN " Belt or chutes.
Detector:
Spectroscopic Grade 3'' x 3'' NaI Scintillation Detector.
(Optional 5'' or 7'' diameter)
Ultimate Sensitivity: 7µ R/hr above background in 1 second.
Background: Automatically subtracted.
Shielding: 2 cm lead over greater than 2Pi. Lead shield is modular and easy to assemble (no piece over 65lbs.)
Electronics: The Scintillation Detector has its own PM tube. PMT base (dynode string circuit) Independent Modular high voltage and pre-amp discriminator. This provides improved sensitivity and easier maintenance if a PM tube is replaced.
Alarms: Alarm threshold is continuously adjustable for each energy channel/Regions of Interest. High level alarm is user settable. Alarms are audio and visual plus screen display.
Operation: Selectable: Continuous Mode, Calibration Mode
Computer System: Pentium IV 1 Giga Hz. High Resolution Graphics Display 1024 x 768, 256 colors. Color LCD screen monitor on a movable arm for improved ergonomics.
Record Keeping: All data automatically stored on 60 Gig hard drive. Data can be transmitted to other PC's by built in Ethernet connection (Optional: Telephone Modem). Graphics printer included. User can print tabular or graphical records of current day, week, month or year.
Conveyor Speed: Continuously variable, user controlled. 150 mm/sec typical.
Useful Width: 24'' (610mm).
System Weight: 175 Kg plus Shielding.
Conveyor System: 2 each conveyors. Belt #1 is 6 ft. long, (typical) belt carries packages beside detector. Belt #2 is 4 ft. long, (typical) reversible direction conveyor, drops CLEAN packages to one side and drops off RADIOACTIVE/CONTAMINATED packages on the other side.
Optional: Additional conveyors to carry away ``CLEAN'' & ``RADIOACTIVE'' Packages.
Environmental Conditions: 45^oF to 100^oF, (8^o to 38^oC) 10% to 95% relative humidity, non-condensing.
Power Supply: 100 - 120 V AC or 220 V 50/60 Hz with UPS.
